TECHNICAL FIELD

The present disclosure relates generally to devices using liquidinhalable precursors. More specifically, and without limitation, thepresent disclosure relates to devices for vaping and methods ofmanufacturing such devices.

RELATED ART

Vaping devices, also referred to herein as vaping devices (EVDs), may beused for portable vaping. An vaping device may vaporize a pre-vaporformulation, such as an oil that may or may not contain one or morecannabinoids, to form a vapor. The e-vaping device may include areservoir that holds a pre-vapor formulation and a heating element thatvaporizes the pre-vapor formulation by applying heat to at least aportion of the pre-vapor formulation. Vaping devices are often sold andshipped directly to local oil manufacturers, and then filled with apre-vapor formulation, and capped by the local oil manufacturers.

Filling and capping may be done by hand, or it may be automated. Forautomated filling and capping, the mouthpiece must be able to beeffectively and securely attached by machine to the reservoir. Themouthpiece and associated structures must plug the reservoir to ensurethat no pre-vapor formulation can spill out of the reservoir.

There is a need for improved design of an EVD that has a simple, secure,and reliable structure to lock the mouthpiece onto the reservoir.

Certain components of the vaping system described herein will bedescribed as being coupled or connected to one another and suchconnections and couplings may be achieved in any suitable manner.Additionally, such components may be integrated with one another ordistributed in any suitable fashion. As used herein, the vaping systemmay be described as having parts or portions that are more proximal andparts or portions which are more distal. This is relative to thedistance from a user's mouth with the vaping system is in use. Forexample, the mouthpiece of the vaping system will be more proximal, oron a proximal end of the vaping system. In one configuration, a portionor feature of the system which is towards the proximal end is closer tothe proximal end than the distal end. Similarly, in an exemplaryconfiguration, a portion or feature of the system which is towards thedistal end is closer to the distal end than the proximal end.

This disclosure generally relates to systems and methods for improvedvaping systems. According to one aspect, an vaping system 10 (FIGS. 1-2) generally includes: a cartridge tank 15 or body with an interiorreservoir to be filled with oil or another liquid for vaping; acartridge base 19 for attachment to a distal end of the tank 15, whichmay hold an atomizer housing 24 that includes an atomizer or heatingelement for heating oil to create vapor; a locking sheath 25 forconnecting the cartridge tank 15 to the mouthpiece; and a mouthpiece 30for attachment to a proximal end of the tank 15 and sealing the tank 15closed.

The tank 15 has a proximal end 31 for connection to the mouthpiece 30and a distal end 32 for connection to the cartridge base 19. The base 19may include a means for connection to a battery to provide power to theheating element (shown, by way of example, as threaded distal projection33 in FIG. 1 ).

Holes 37 in the distal base portion 39 of the atomizer housing 24 allowoil from the reservoir of the tank 15 to enter the atomizer housing 24,contact one or more heating elements, and be heated into vapor. As theoil is vaporized, it travels upward through the central lumen 38, fromthe distal end 42 of the central lumen 38 to the proximal end 45 of thecentral lumen 38 to the mouthpiece 30 to be inhaled by the user. Thevaping system 10 may include one or more gaskets or seals 75 between themouthpiece 30 and the tank 15 to ensure the oil or other pre-vaporformulation does not leak out the mouthpiece 30.

The central lumen 38 of the atomizer housing includes one or more ridges47 at or near the proximal end 45. The configuration illustrated in FIG.2 includes three ridges: first ridge 47 a for interfacing with a lockingsheath, as described in more detail below, a second ridge 47 b and athird ridge 47 c. The space formed between the second and third ridgesmay receive a gasket. Instead of three ridges, one ridge, two ridge, orfour or more ridges may be provided. Gaskets may be placed betweenridges or may be left as open space.

Referring to FIGS. 3-5 , locking sheath 25 includes a proximal end 51for interfacing with the mouthpiece 30, and a distal end 55 opposite theproximal end. Distal end 55 may form a distal flange 58 (FIGS. 4-5 ). Inother configurations, a distal flange 58 is not provided. A sidewall 62of the locking sheath 25 extends from the proximal end 51 to the distalend 55 and forms a substantially hollow interior. The sidewall 62includes an interior side 65 forming a lumen and an exterior side 69.

One or more structures may be attached to, or formed integrally with thelocking sheath 25. Medial ridge 72 extends from the exterior side 69outwardly. The medial ridge 72 interfaces between the proximal end 31 ofthe cartridge tank 15 and the distal end 78 of the mouthpiece 30 (FIGS.7-8 ). The space formed between the distal flange 58 and medial ridge 72may receive a sealing gasket 75. In other configurations no sealinggasket is provided, and in some configurations, no medial ridge 72 isprovided on the locking sheath 25.

The locking sheath 25 includes one or more teeth 80 for locking thelocking sheath into place on the proximal end 45 of the central lumen38. FIGS. 3-5 illustrate a locking sheath 25 with exactly three teeth,spaced equidistant apart. In other configurations, two or fewer teethmay be provided, and in yet other configurations, four or more teeth maybe provided, such as four or five teeth. Teeth 80 extend inwardly fromthe interior side 65 of the sidewall 62 of the locking sheath 25, ortowards the lumen 26 formed by the interior of the locking sheath 25.The teeth 80 may thus be located within a lumen 26 of the locking sheath25. Teeth may be formed integrally with the locking sheath 25, or teethmay be otherwise connected to locking sheath 25. The interior side 65 ofthe sidewall 62 may form an interior shelf 84, and teeth 80 may extendproximally and inwardly from the interior shelf 84.

With reference to the top view of FIG. 4 , in configurations withexactly three teeth 80 spaced equidistant apart, the width of the teeth80 may be approximately equal to the space 87 between the teeth. Thatis, the three teeth 80 may each have a width of about one-sixth of thecircumference of the inner lumen of the locking sheath 25. Three teeth80 may also provide a more even balance for the locking mechanism,similar to a tripod. Instead of the width of the teeth 80 being equal tothe space 87 between the teeth, the teeth may be more narrow (i.e.,providing more space 87 between the teeth 80), or the teeth may be morewide (i.e., providing less space 87 between the teeth 80).

The space between the teeth 80 may allow for additional flexing of theteeth 80. However, too much space between teeth 80 may not provideenough structural support and rigidity. Additionally, in configurationswith an even number of teeth 80 that are spaced equidistant apart (suchas two or four teeth), it may create spaces which are directly oppositeeach other within the lumen of the locking sheath 25 and causestructural weakness. In configurations with exactly three teeth spacedequidistant apart, there is no point on the inner lumen of the lockingsheath that is not either covered by one of teeth 80 or is immediatelyopposite one of teeth 80. This is in contrast, for example, toconfigurations with four teeth, where there are spaces which aredirectly opposite other spaces, creating potential structural weakness.

Teeth 80 may interface with the proximal ridge 47 a of the central lumen38. For example, as the locking sheath 25 is placed over the centrallumen 48, teeth 80 may engage the ridge 47 a, be pushed outwardly by theridge 47 a, and then resiliently return to their resting position, belowthe ridge 47 a. Each of the teeth 80 may have a sloped underside toencourage the teeth to be pushed outwardly by the ridge 47 a as theridge 47 a engages the teeth from the bottom to be attached. Onceattached, the flat top side of the teeth interfaced against the flatbottom side of the ridge 47 a ensures that the locking sheath 25 cannotbe removed.

The proximal end 51 of the locking sheath 25 may abut the interior ofthe mouthpiece 30. Mouthpiece 30 has an external wall 90 surrounding asubstantially hollow lumen. Mouthpiece 30 further has an interior guidelumen 92 for guiding vapor from the central lumen 38 of the atomizerhousing 24 to a user's mouth. A slot 95 (best seen in FIG. 10 ) betweenthe interior guide lumen 92 and the external wall 90 receives theproximal end 51 of the locking sheath 25. The slot 95 is shaped tofrictionally fit the proximal end 51 of the locking sheath 25. Glue,ultrasonic welding, or other suitable connection means may also be usedto connect the proximal end of the locking sheath 25 to the mouthpiece30. In other configurations, the mouthpiece 30 is substantially hollowand not provided with an interior guide lumen.

In one configuration, the proximal end 51 of the locking sheath has anotch 97 formed therein. In configurations where the locking sheath 25is formed by injection molding plastic, the notch 97 may be whereplastic is injected into the mold. The notch 97 creates a pocket or voidto inject plastic into the mold and reduce any excess plastic withoutprotruding from the height of the part. Excess plastic protruding abovethe height of the proximal end 51 can cause issues such as reducing thefit between the proximal end 51 of the locking sheath 25 and the slot 95of the mouthpiece. In other configurations, instead of a notch 97, theproximal end 51 may be flat and not provided with a notch.

The locking sheath 25 may be formed of a variety of materials and in avariety of ways. Injection molding plastic may be used to form all orpart of the locking sheath. The locking sheath 25 could be cut from aplastic or metal. All or part of the locking sheath may be formed frommetal or other suitable materials known in the art. In otherconfigurations, the locking sheath may be provided with teeth formed ofmetal, such as a spring steel snap with metal teeth. The spring steelsnap may be formed of stamped metal.

The locking sheath 25 includes one or more ribs 99 formed in theexterior side 69 of the sidewall 62 between the medial ridge 72 and theproximal end. The ribs 99 form voids 98 that can receive excess glue inconfigurations where the locking sheath 25 is glued to the mouthpiece30. One rib 99 may be provided, or two or three or more ribs 99 may beprovided. Instead of ribs 99, the locking sheath 25 may have asubstantially smooth exterior side 69 of the sidewall 62 without ribs99.

Mouthpiece 30 may be fit to the tank in any suitable manner. Themouthpiece 30 may be non-removably attached to the tank 15 to ensure aone-way tamper resistant fit. The mouthpiece 30 may be non-removablyattached to the tank 15 by press fitting the locking sheath 25 against aridge 47 a of the central lumen 38. In this type of configuration, thecentral lumen 38 of the atomizer housing 24 may be provided with one ormore ridges 47. Ridges 47 may extend outwardly from the central lumen38, and in one configuration may be burred or otherwise shaped tofacilitate a one-way connection. This burred proximal end 45 of thecentral lumen 38 may provide a 1-way connection to the mouthpiece 30,such that when the mouthpiece 30 and associated locking sheath 25 ispressed downward onto the burred proximal end 45, it cannot be removed.This one-way press-fit design may be tamper-resistant. It will beappreciated that this burred proximal end 45 of the central lumen 38 maybe used in conjunction with other designs as described herein.

With reference to FIGS. 11-12 , another configuration of a lockingsheath 250 is shown. Several ribs 990 are provided between the medialridge 720 and the proximal end 510.
